Product description:

20 b multiplex signal/verification instrument that can simulate all kinds of industrial process of sensor and transmitter, can lose 11 standard signals at the same time, also can be measured signals produced by some process instrumentation, therefore is suitable for a new generation of automation instrument, automatic control system commissioning and validation.Because JK - 20 b is equipped with 24 VDC output for adjustable two wire measurement instrument, so use the JH - 20 b multiplex signal after verification without having to match other instruments can be easily and accurately for more than one instrument for debugging and testing at the same time.
